Description

  The present invention relates to a versatile screen device that can be used as a curtain, a blind, a screen door, and a partition.

  The present applicant provides a screen device as a device that eliminates the restrictions of installation when used as light shielding and light control means such as curtains and blinds, screen doors, partitions, etc., and realizes a smooth and stable opening and closing operation. (Patent Document 1).

  In the screen device described in Patent Document 1, a screen is attached to a pair of screen mounting frame portions, which are arranged to face each other and at least one of which is slidable, so that the screen can be contracted and expanded between both screen mounting frame portions. In addition, a pair of slide guide frame portions are disposed in the vicinity of both ends of the screen that are not attached to the screen mounting frame portion. The slide guide frame is formed by a rigid unit having a pair of side walls arranged opposite to each other and a bridging part connecting the side walls to each other so as to be rotatable in adjacent two. The slide guide frame portion is flexible, and at least one end is a free end so that the slide guide frame portion can be stored and pulled out in the screen mounting frame portion. The portion of the slide guide frame pulled out from the screen mounting frame portion with the sliding movement of the screen mounting frame portion maintains linearity. By such a slide guide frame part, the restriction of installation is eliminated and a smooth and stable opening / closing operation is realized.

  The screen device can be manufactured to have a desired size according to the size of an opening such as a window or a door frame, for example, but it is large, particularly a width in the opening / closing direction, that is, a screen mounting frame portion. The following problems are pointed out when the width of the slide movement direction is large.

  When the screen is unfolded and the screen device is closed, the screen may be greatly bent by the wind pressure when receiving strong wind. When the screen is greatly bent as described above, a large gap is formed between the slide guide frame portion, and the functions of the screen device such as light shielding property and insect-proofing property are impaired.

  Further, in the screen device in which the slide guide frame portion is disposed near the upper and lower ends of the screen, the upper slide guide frame portion drawn out from the screen mounting frame portion is supported from below by the rigidity of the screen. However, as the width in the opening / closing direction increases, the upper slide guide frame portion drawn out from the screen mounting frame portion becomes longer, so that it is expected to be bent by its own weight. This bending of the slide guide frame part hinders the opening / closing operation of the screen device.

  Therefore, the present applicant has a pair of vertical supports arranged on both sides of the screen are connected by a connecting member, fixed between a pair of slide guide frame parts with the screen sandwiched therebetween, As a unit, a screen device is proposed that is slidable in a direction parallel to the sliding movement direction of the screen mounting frame (Patent Document 2).

  In the screen device described in Patent Document 2, the connected frame slides as the screen mounting frame portion slides, and reinforces the surface strength of the screen developed between the pair of screen mounting frame portions. For this reason, even if a strong wind is received, the screen is prevented from being greatly bent by the wind pressure, and functions such as light shielding and insect repellent of the screen device are stably realized. Further, the upper slide guide frame provided near the upper end of the screen is prevented from being bent by its own weight, and the opening / closing operation of the screen device is stably realized.

FIG. 2 is an exploded perspective view of a main part showing a peripheral portion of the screen device shown in FIGS. 1 (a) and 1 (b). 3A, 3B, and 3C are a front view, a plan view, and a side view, respectively, showing the connection unit of the screen device shown in FIGS. 1A and 1B in an enlarged manner.

  The screen device 1 shown in FIGS. 1A and 1B and FIG. 2 includes a pair of screen mounting frame portions 2a and 2b. The screen mounting frame 2a is fixed to the right side of the inner edge of the opening. On the other hand, the screen attachment frame portion 2b is disposed so as to be slidable in the lateral direction of the opening toward the left side of the inner edge of the opening, and both the screen attachment frame portions 2a and 2b are arranged to face each other. On the upper side of the inner edge of the opening, the upper rail 3 is disposed along the lateral direction of the opening, and the upper ends of the screen mounting frame portions 2a and 2b are housed inside the upper rail 3. A lower rail 4 is disposed below the inner edge of the opening along the lateral direction of the opening. The movable screen mounting frame portion 2 b is slidable in the lateral direction of the opening along the upper rail 3 and the lower rail 4.

  A screen 5 formed of a net is attached between the screen attachment frame portions 2a and 2b. The screen 5 is pleated by pleating, and can be contracted and expanded between the screen mounting frame portions 2a and 2b. That is, when the screen mounting frame 2b slides to the left of the inner edge of the opening, the screen 5 expands into the opening and prevents insects and the like from entering. Further, the screen 5 contracts when the screen mounting frame portion 2b slides toward the right side of the inner edge of the opening, and is folded and stored between the screen mounting frame portions 2a and 2b.

  The screen 5 can be formed from a net, a cloth, a resin sheet, or the like, and can be formed from an appropriate material according to the use of the screen device 1. In addition to pleating by pleating, it can be contracted and expanded by, for example, a honeycomb structure.

  A tension member 6 extending in the contracting and expanding directions is stretched on the screen 5. As the tension member 6, an appropriate member that generates tension such as a string or a wire can be adopted, and the tension member 6 can be arranged at a plurality of positions at a predetermined interval corresponding to the height of the screen 5. Such a tension member 6 penetrates the pleated screen 5 in the shrinking and unfolding directions and supports the screen 5. The screen 5 is secured by the tension member 6 and has a high surface strength.

  Further, the screen device 1 includes a pair of slide guide frame portions 7a and 7b at both ends of the screen 5 that are not on the attachment side to the screen mounting frame portions 2a and 2b, that is, near the upper and lower ends. The slide guide frame portions 7a and 7b are both formed by connecting two slide guide frame portion units 8 together. The slide guide frame unit 8 is formed by connecting a plurality of rigid units 9 and has a predetermined length.

  The rigid unit 9 has a pair of side wall portions 10 arranged to face each other and a bridging portion 11 that connects the side wall portions 10 to each other. The side wall 10 is provided with a protrusion 12 protruding outward at one end in the length direction, and a through-hole 13 with which the protrusion 12 can be engaged is formed at the other end. Further, the side wall portion 10 is provided with a small protrusion 14 which is located on the opposite side of the through hole 13 adjacent to the protrusion 12 and protrudes to the outside, and on the side of the protrusion 12 adjacent to the through hole 13. A substantially crescent-shaped elongated hole 15 is formed. Such two rigid units 9 can be rotated by inserting the projections 14 into the through-holes 13 from the inside of the side wall 10 and engaging the small projections 14 in the long holes 15 in two adjacent units. The slide guide frame unit 8 is formed continuously. The slide guide frame unit 8 is flexible because the two rigid units 9 are rotatable adjacent to each other, and has a bend, and the small protrusion 14 contacts one end of the long hole 15 in the length direction. The linearity can be maintained by restricting the rotation of the rigid unit 9. In order to maintain the linearity of the slide guide frame unit 8, the rigid unit 9 can further be provided with a step by notching the surface of one end edge of the bridging portion 11 and the back surface of the other end edge, It is also possible to restrict the rotation of the rigid unit 9 by superimposing a step in conjunction with the contact of the small protrusion 14 with the long hole 15.

  Two such slide guide frame unit 8 are connected by a connecting unit 16 at one end. As shown in FIGS. 3A, 3 </ b> B, and 3 </ b> C, the connecting unit 16 includes a pair of side wall portions 17 that are opposed to each other and a bridging portion 18 that connects the side wall portions 17 to each other. . The side wall portion 17 is provided with protrusions 19 protruding outward at both ends in the length direction. The protrusions 19 have substantially the same shape and size as the protrusions 12 of the rigid unit 9. The through hole 13 can be engaged. Further, a small protrusion 20 located on the edge side adjacent to the protrusion 19 is disposed on the side wall portion 17. The small protrusion 20 can be engaged with the long hole 15 of the rigid unit 9.

  The two slide guide frame unit 8 is engaged with the through hole 13 of the rigid unit 9 located at one end of the slide guide frame unit 8 by fitting the projection 19 of the connecting unit 16 from the inside and engaging the small projection 20 in the long hole 15. By being fitted and engaged from the inside, they are connected via the connecting unit 16 to form slide guide frame portions 7a and 7b. For this reason, both the slide guide frame portions 7a and 7b have flexibility and can maintain linearity, similarly to the slide guide frame unit 8.

  Such slide guide frame portions 7a and 7b have both ends in the length direction, that is, one end of the slide guide frame unit 8 that is not connected by the connecting unit 16 as a free end, and the screen mounting frame portion 2a, 2b can be stored and pulled out. When the screen mounting frame 2b is slid in the lateral direction of the opening toward the left side of the inner edge of the opening, the slide guide frame 7a, 7b is pulled out from the screen mounting frame 2a, 2b, and the pulled out portion is a straight line. Retain sex. On the other hand, when the screen mounting frame portion 2b is slid toward the right side of the inner edge of the opening, the slide guide frame portions 7a and 7b bend at the upper and lower end portions of the screen mounting frame portions 2a and 2b. It is housed inside the parts 2a, 2b. Such storage and drawing of the slide guide frame portions 7a and 7b is performed along the upper rail 3 and the lower rail 4, and the upper slide guide frame portion 7a is stored and pulled out at the lower end of the upper rail 3. Is done inside.

  The connecting unit 16 is disposed so as to face the upper and lower sides of the pair of slide guide frame portions 7a and 7b.

  In the screen device 1 shown in FIGS. 1A and 1B and FIG. 2, one vertical stand 21 is provided between the screen 5 and the tension member 6 on the surface side of the screen, and the pair of slide guide frame portions 7 a. , 7b. The vertical frame 21 has a circular pipe shape, and is fixed to the connection unit 16 at one end and the other end using a rivet 22a as a fixing member 22. As will be described later, the stand 21 can be fixed to the connecting unit 16 in a removable manner.

  In the screen device 1, another stand 24 is provided with a gap 23 and a gap 23 with the tension member 6 interposed therebetween. The stand 24 matches the size, shape and length of the stand 21. Similarly to the vertical frame 21, the vertical frame 24 is detachably fixed to the connecting unit 16 at one end and the other end using a rivet 22a. The two vertical stands 21 and 24 are connected by a bridging member 25 having elasticity at three positions in the length direction where the tension member 6 is not located.

  As shown in FIG. 2, the bridging member 25 includes two cylindrical fitting piece portions 26 having a substantially C-shaped cross section and a flat plate-like connecting piece portion 27 that connects the two fitting piece portions 26. And. In the bridging member 25, the two fitting piece portions 26 both have an inner diameter that matches the outer diameter of the vertical shapes 21 and 24, and the fitting piece portion 26 is formed with a notch 28. In the bridging member 25, the notch portion 28 is disposed oppositely, and the two fitting piece portions 26 are connected by the connecting piece portion 27. Moreover, when the notch part 28 is expanded, the fitting piece part 26 will elastically deform so that an internal diameter may expand. Therefore, in the bridging member 25, when the uprights 21 and 24 are inserted inside the fitting piece portion 26 through the notch 28, the fitting piece portion 26 is fitted so as to be wound around the outer periphery of the uprights 21 and 24. Both the vertical stands 21 and 24 are connected by the bridging member 25. The two uprights 21 and 24 connected in this way are arranged with a gap 23 having a size equal to the width of the connecting piece 27, and the tension member 6 can be passed through the gap 23.

  The double stands 21 and 24 arranged so as to be bridged between the pair of slide guide frame portions 7a and 7b are accommodated by the slide guide frame portions 7a and 7b being retracted and retracted as the screen mounting frame portion 1b slides. , And slide together in a direction parallel to the sliding movement direction of the screen mounting frame 1b. Even if there is a gap 23 between the two vertical stands 21, 24, the rigidity is increased by the connection by the bridging member 25, and the sliding movement of the vertical stands 21, 24 is stably realized. By means of the double stands 21, 24, the surface strength of the screen 5 developed between the pair of screen mounting frame portions 2a, 2b can be reinforced. For this reason, in the case of the large screen device 1 having a large width in the opening and closing direction, even if a strong wind is received in the closed state, the screen 5 can be prevented from being greatly bent by the wind pressure, and the screen device 1 is shielded from light. Functions such as safety and insect repellent are realized stably.

  Further, the upper slide guide frame portion 7 a is sufficiently supported by the screen 5 that is suppressed from being largely bent, and is also supported by both the vertical stands 21 and 24. For this reason, it is suppressed that the part pulled out from the screen attachment frame parts 2a and 2b of the slide guide frame part 7a is bent by its own weight, and the opening / closing operation of the screen device 1 is stably realized.

  Further, in the screen device 1, as shown in FIG. 3A, the bridging portion 18 of the connecting unit 16 has two first holes 29 at intervals in the width direction at the central portion in the length direction. Is formed. A second hole 30 is formed continuously with the first hole 29. The first hole 29 is narrow and the second hole 30 is wide. The width of the first hole 29 is slightly larger than the outer diameter of the shaft portion of the rivet 22a shown in FIG. 2, and the width of the second hole 30 is slightly larger than the outer diameter of the head of the rivet 22a. Inside the second hole 30, a tongue piece 31 extending from an edge located on the opposite side to the first hole 29 is disposed. The size of the tongue piece 31 is slightly smaller than the second hole 30, and one end on the first hole 29 side is a free end. The tongue piece 31 has elasticity, can be pushed and bent, and allows the second hole 30 to be opened and closed.

  FIG. 4 is a perspective view of a main part showing the release of the vertical fixing from the connecting unit in the screen device shown in FIGS. 5A and 5B are a plan view corresponding to FIG. 4 and a cross-sectional view taken along line AA.

  The vertical frames 21 and 24 are fixed to the connecting unit 16 of the upper slide guide frame portion 7a by a rivet 22a attached to one end thereof, and the lower slide guide frame portion 7b is connected by a rivet 22a attached to the other end thereof. It is fixed to the unit 16. In the fixed state, the shaft portion of the rivet 22a is located in the first hole 29 formed in the bridging portion 18 of the connecting unit 16, and is between the head of the rivet 22a and one end and the other end of the vertical plates 21 and 24. The bridging portion 18 is sandwiched between them.

  When the rivet 22a is slid from the first hole 29 to the second hole 30, the head of the rivet 22a pushes and bends the tongue piece 31. That is, in the connecting unit 16 of the upper slide guide frame portion 7a, when the rivet 22a is slid from the first hole 29 to the second hole 30, the head of the rivet 22a sinks under the tongue piece 31, and the tongue piece 31 is Push up from the bottom. By this pushing up, the tongue piece 31 is elastically deformed and is bent upward. Further, in the connecting unit 16 of the lower slide guide frame portion 7b, when the rivet 22a is slid from the first hole 29 to the second hole 30, the head of the rivet 22a rides on the tongue piece 31, and the tongue piece 31 is pushed down from the upper side. The tongue piece 31 is elastically deformed by this depression and is bent downward. At this time, the second hole 30 is opened. As described above, since the width of the second hole 30 is slightly larger than the outer diameter of the head of the rivet 22 a, the uprights 21 and 24 are released from the connection unit 30. The uprights 21 and 24 can be removed by pulling down the connecting unit 16 of the upper slide guide frame 7a and pulling up the connecting unit 16 of the lower slide guide frame 7b.

  As described above, in the screen device 1, the two frames 21 and 24 do not sandwich the screen 5, and the rivet 22 a as the fixing member 22 is bridged with the connecting unit 16 of the slide guide frame portions 7 a and 7 b. By sliding the first hole 29 formed in the portion 18 from the first hole 29 to the second hole 30, the vertical frames 21 and 24 can be removed from the slide guide frame portions 7a and 7b without using a tool. In this case, it is possible to easily remove the frames 21 and 24 performed prior to that. For this reason, it is easy to remove the screen 5. In addition, since the double stands 21 and 24 are connected by the bridging member 25 as described above, the bridging member 25 can be removed without using a tool, and the double stands 21 and 24 can be easily separated. . After removing the vertical supports 21 and 24, the tongue piece 31 returns to its initial state in the connecting unit 16 due to its elasticity. The second hole 30 is closed.

  In addition, attachment to the slide guide frame parts 7a and 7b of the stand 21 and 24 can be performed in the procedure reverse to removal. In the attached state of the uprights 21 and 24, the first hole 29 formed in the bridging portion 18 of the connecting unit 16 is closed by the head of the rivet 22a, and the second hole 30 is closed by the tongue piece 31. . For this reason, it is suppressed that light leaks through the first hole 29 and the second hole 30 or insects enter, and the functions of the screen device 1 such as the light shielding property and the insect proofing property are stably realized.

  6A and 6B are a front view and an upper cross-sectional view, respectively, showing a second embodiment of the screen device of the present invention. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals in FIGS. 6A and 6B, and description thereof will be omitted below.

  In the screen device 32, the stand 24 in the screen device 1 shown in FIGS. 1A and 1B is omitted, and one stand 21 is provided between the screen 5 and the tension member 6 on the surface side of the screen 5. A pair of slide guide frame portions 7a and 7b are arranged so as to be bridged. Even with only the stand 21, the screen device 32 can reinforce the surface strength of the screen 5 and suppress the deflection of the screen 5 due to wind pressure. Further, the upper slide guide frame portion 7a supported by the screen 5 can be sufficiently supported by the vertical frame 21, and the bending due to the weight of the slide guide frame portion 7a can also be suppressed. Further, since the screen 24 is omitted from the screen device 32, the screen 21 can be easily removed prior to the removal of the screen 5, and the screen 5 can be removed more easily.

  The present invention is not limited by the above embodiment. Various aspects are possible for details such as the structure of the screen mounting frame, the shape of the frame, and the way of passing the tension member through the screen. In the screen devices 1 and 32 shown in FIGS. 1A and 1B and FIGS. 6A and 6B, the screen mounting frame 1a is not fixed to the right side of the inner edge of the opening, but the screen mounting frame 1b.
